Act: local js action fails (uses: ./)

[helaili]

When developing a new JS action, I like to create a workflow within the same repo so I can test various use cases. In such a case, I reference the local action with - uses: ./ as defined in the documentation

on: [push]
jobs:
  hello_world_job:
    runs-on: ubuntu-latest
    name: A job to say hello
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - uses: ./
        with:
          who-to-greet: 'Mona the Octocat'

Unfortunately, it fails with the following error:

internal/modules/cjs/loader.js:628
|     throw err;
|     ^
| 
| Error: Cannot find module '/github/workspace/aws-instance-ripper/index.js'
|     at Function.Module._resolveFilename (internal/modules/cjs/loader.js:625:15)
|     at Function.Module._load (internal/modules/cjs/loader.js:527:27)
|     at Function.Module.runMain (internal/modules/cjs/loader.js:839:10)
|     at internal/main/run_main_module.js:17:11 {
|   code: 'MODULE_NOT_FOUND',
|   requireStack: []
| }

It does work if I move the action code in an action subfolder and use it with - uses: ./action.

This can be reproduced with the sample hello-world-javascript-action, you just need to add a basic workflow.

Hey, I had the same issue, but already posted my solution in #228. You need to provide the path parameter to the actions/checkout action in order to get the correct path when the code is copied to the container.

Sorry if this belongs in a new issue, but I'm experiencing a very similar problem in a similar situation. I'll be glad to open a new issue, if that would be better....

It looks like act is not resolving relative paths within local actions the same way that GitHub Actions does.

For instance, I have a workflow referencing a local action....

      - name: Auth0 deployment
        uses: ./.github/actions/auth0-deploy

And my action.yml file in that directory looks like this:

name: auth0-deploy
inputs:
  prod-branch:
    description: Name of the branch to consider "production". Default is "master".
    required: false
runs:
  using: node12
  main: 'dist/index.js'

When I run locally, I get the same kind of stack trace:

| internal/modules/cjs/loader.js:628
|     throw err;
|     ^
| 
| Error: Cannot find module '/github/workspace/dist/index.js'
|     at Function.Module._resolveFilename (internal/modules/cjs/loader.js:625:15)
|     at Function.Module._load (internal/modules/cjs/loader.js:527:27)
|     at Function.Module.runMain (internal/modules/cjs/loader.js:839:10)
|     at internal/main/run_main_module.js:17:11 {
|   code: 'MODULE_NOT_FOUND',
|   requireStack: []
| }

However, this configuration is valid per the GHA documentation, and the workflow runs successfully on GitHub. act should be resolving my action's main script to /github/workspace/.github/actions/auth0-deploy/dist/index.js, instead of just /github/workspace/dist/index.js.

Issue is stale and will be closed in 7 days unless there is new activity

Can this be reopened? I've confirmed this use case breaks for me:

      - name: checkout foo
        uses: actions/checkout@v2
        path: .github/actions/foo

      - name: use foo
        uses: ./.github/actions/foo

Gets

Error: open /path/to/users/pwd/.github/actions/foo/action.yaml: no such file or directory

should resolve to

github/workspace/.github/actions/foo/action.yaml
